Mark,
Clearly, all you need to do is poke another hole in the hull to let all the water filling the hull out. I

Capture some of that energy with a water-wheel, then use some of THAT energy to pump out the water filling up your boat. Boat soon sinks anyway.

> With a moving boat, something is putting extra energy into the boat to move it. You can steal some of that energy by dragging a generator with a propeller behind the boat on a long rope. Or sticking a water-wheel over the side, like last century's river paddle-wheelers (some still in operation). Or poking a hole in the hull and putting a scoop under it to force high pressure water through a generating turbine, like those made for off-grid homes near streams.
